policy to contribute, please send e-mail to stephen@sans.edu

1.0 Purpose
The Email Retention Policy is intended to help employees determine what information sent or received by
email should be retained and for how long.

The information covered in these guidelines includes, but is not limited to, information that is either stored
or shared via electronic mail or instant messaging technologies.

All employees should familiarize themselves with the email retention topic areas that follow this
introduction.


Questions about the proper classification of a specific piece of information should be addressed to your
manager. Questions about these guidelines should be addressed to Infosec.

2.0 Scope
This email retention policy is secondary to <Company Name> policy on Freedom of Information and
Business Record Keeping. Any email that contains information in the scope of the Business Record
Keeping policy should be treated in that manner. All <Company Name> email information is categorized
into four main classifications with retention guidelines:
Administrative Correspondence (4 years)
Fiscal Correspondence (4 years)
General Correspondence (1 year)
Ephemeral Correspondence (Retain until read, destroy)



3.0 Policy
     3.1 Administrative Correspondence
     <Company Name> Administrative Correspondence includes, though is not limited to clarification of
established company policy, including holidays, time card information, dress code, work place behavior
and any legal issues such as intellectual property violations. All email with the information sensitivity
label Management Only shall be treated as Administrative Correspondence. To ensure Administrative
Correspondence is retained, a mailbox admin@<Company Name> has been created, if you copy (cc) this
address when you send email, retention will be administered by the IT Department.

     3.2 Fiscal Correspondence
     <Company Name> Fiscal Correspondence is all information related to revenue and expense for the
company. To ensure Fiscal Correspondence is retained, a mailbox fiscal@<Company Name> has been
created, if you copy (cc) this address when you send email, retention will be administered by the IT
Department.
    3.3 General Correspondence
    <Company Name> General Correspondence covers information that relates to customer interaction
and the operational decisions of the business. The individual employee is responsible for email retention of
General Correspondence.

    3.4 Ephemeral Correspondence
    <Company Name> Ephemeral Correspondence is by far the largest category and includes personal
email, requests for recommendations or review, email related to product development, updates and status
reports.

     3.5 Instant Messenger Correspondence
     <Company Name> Instant Messenger General Correspondence may be saved with logging function of
Instant Messenger, or copied into a file and saved. Instant Messenger conversations that are Administrative
or Fiscal in nature should be copied into an email message and sent to the appropriate email retention
address.

    3.6 Encrypted Communications
    <Company Name> encrypted communications should be stored in a manner consistent with
<Company Name> Information Sensitivity Policy, but in general, information should be stored in a
decrypted format.

     3.7 Recovering Deleted Email via Backup Media
     <Company Name> maintains backup tapes from the email server and once a quarter a set of tapes is
taken out of the rotation and they are moved offsite. No effort will be made to remove email from the
offsite backup tapes.

4.0 Enforcement

termination of employment.
